Consistency between the measurements for different foil thicknesses and aperture sizes. This represents the percentage difference between [μ/ρ] of the individual foil and aperture measurements and their weighted mean at each of the energies. The 10 µm- and 12 µm-thick foils showed relatively good consistency at energies lower than 5.6 keV and consistency with the thinnest foil (5 µm) was found to be excellent throughout the energy range of measurements. A 10–25% harmonic contamination was found at lower energies, <8 keV, and correction was made to attain good consistency. The thickest foil (12 µm) in this energy range was affected most by the harmonic content.
